Abstract

EL CONTADOR CONTIENE UNA PARTE MEDIDORA Y OTRA EVALUADORA (1). LA PRIMERA CONTIENE UN INTERCAMBIADOR DE CORRIENTE MAGNETICO (3), DEL TIPO DE UN TRANSFORMADOR SIN CARGA Y UN INTEGRADOR CONECTADO CON ESTE (6). POR ELLO NO SE PRODUCEN EN EL INTERCAMBIADOR FALLOS DE MEDICION CAUSADOS POR SATURACION Y LA MEDICION DEL CONSUMO ES INDEPENDIENTE DE LAS FRECUENCIAS.THE METER CONTAINS A MEASURING PART AND ANOTHER EVALUATOR (1). THE FIRST CONTAINS A MAGNETIC CURRENT EXCHANGER (3), OF THE TYPE OF A NO-LOAD TRANSFORMER AND AN INTEGRATOR CONNECTED WITH IT (6). THEREFORE, MEASURING FAILURES CAUSED BY SATURATION DO NOT OCCUR IN THE EXCHANGER AND THE MEASUREMENT OF CONSUMPTION IS INDEPENDENT OF FREQUENCIES.
